w JERSEY, Assrenon TO AMERICAN TYPE FOUNDERS COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY ADJUSTABLE T01? FOR TYPE CABINETS Application filed December 10,1928. Serial No. 325,015.

This invention relates to adjustable tops for type cabinets.

An object of the invention is to provide an adjustable top with improved means for adjusting the same and securing the same at any desired elevation in accordance with the height of the user or users.

It is an important consideration in setting type to have the top of the cabinet at the proper elevation; or, in other words, the operator or student in accordance with his height must be so best results.

Heretofore with ordinary equipment it has been the practice to provide boxes or stools for short students or operators to stand upon, and I have conceived the idea broadly of providing a' type cabinet with an adjustable top so that the top may be adjustable vertically and securely held at the desired position thus doing away with the necessity for boxes, stools or other devices for the use of operators.

. Furthermore, my invention includes a novel construction of top operating means therefor, and means for securing the same rigidly at the desired elevation.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a perspective view showing my improved adjustable top in operative position on a type cabinet;

Figure 2 is an enlarged detail view in section showing the manner of transmitting motion from the drive shaft to one of the vertical screws for adjusting the top vertically;

Figure 3 is a view in longitudinal section through the cabinet and top, the view being taken in section on the line 33 of Figure 4;

Figure 4 is a View in section on the line 4-4 of Figure 3;

Figure 5 is a fragmentary sectional plan view showing the power transmitting mechanism to adjust the top.

A represents a type cabinet of standard positioned as to secure the construction and B my improved adjustable top located above or on the cabinet A. This top B is preferably of the double type, that is to say, it-has inclined surfaces 1, 1 tapering from the central portion of the top downwardly and having upwardly upstanding flanges 2 at its edges so that two workers or students may work from opposite sides of the same top.

End pieces 3 are secured to the top and one of these end pieces 3 has an opening 4 therein for the passage of a drawer 5. The drawer 5 is of triangular shape in longitudinal vertical-section so that it has a taper or. incline and has grooved edges 6 receiving guide flanges 7 on transverse bars 8 fixed to the under part of the top so as to guide the drawer as it-is moved outwardly and inwardly.

The drawer 5 has a hinged outer end 9 which may be swung downwardly out of the way when the drawer is pulled outward, and may be swung upwardly and inwardly to close the opening in the end of the top when the drawer is moved to its inward position, as clearly indicated in Figure 4 of the drawm 's.

i bracket 10 is fixed to the cabinet A and has an upright slotted arm 11 receiving a bolt 12 which is projected through one end of the top B, and has a wing nut 13 thereon so that when the top is adjusted to the desired lelevation this wing nut is screwed home to securely clamp the top to the bracket 10 and secure the top againstaccidental movement.

To move' the top vertically to any desired A adjustment I provide a drive shaft v14 which is located inv the upper portion of the cabinet A and is mounted in bearing brackets 15', 15 spaced apart and secured to the cabinet A. A coupling sleeve 16 is provided on the shaft 14and extends through the wall of the cabinet A so that a removable crank arm 17 may be coupled to the shaft 14 through the medium of said coupling sleeve to turn the shaft, and when the proper adjustment is had the crank arm is removed so as to prevent unauthorized tampering with the device.

The bearing brackets 15 also provide guidance for the vertical movement of vertical screws 18, which at their upper ends are fixed to bars 19 constituting a part of the top B. 7 On these screws 18 are internally screwthreaded worm gears 20 which mesh with I worm gears 21 on shaft 14 so that when shaft 14 is turned the worm gears 21 transmit a rotary motion to the worm gears 20, and as the latter areinternally screw threaded and mesh with the threads of the screws 18, said screws I and the top B are caused to move vertically either up or down in accordance with the direction that the shaft 14 is turnedand the top B is maintained in proper horizontal position at all times.

In use the type boxes 22 constitute drawers of the cabinet A and can be placed on the topB and thesaidtype located in a galley 23 on the drawer 5, as indicated by dotted lines in Figure 1, so that while this is the primary use of the device the invention is of course not limited to such specific utility.

While Lhave illustrated what I believe to be a preferred embodiment of my invention it is obvious various changes and alterations might be made in the general form of the parts described without departing from my invention and hence I donot limit myself to the precise details set forth but consider myself. at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. The combination with a type cabinet, of

a separate top above the cabinet, means for V adjusting the top vertically relative to the cabinet, means for securing the top at any desired adjustment, and aninclined drawer movable through one end of the top.

2. The combination with a type cabinet, of a separate top above the cabinet, means for adjusting the top vertically relative to the cabinet, means for securing the top at any desired adjustment, and an inclined drawer movable through one end of the top, said inclined drawer having a hinged outer end.

3. The combination with a type cabinet, of a separate top above the cabinet, a pair of members secured to the. top and projecting into the cabinet, manually operated means lo.- cated within the cabinet for moving said members vertically, and means for securing the top at any desired adjustment.

4. The combination with a type cabinet, of I a separate top above the cabinet, a pair of members secured to the top and projecting into the cabinet, manually operated means located within the cabinetfor moving said members vertically, a slotted bracket secured to the cabinet, a bolt carried by the movable top and movable in said slotted bracket, and a nut on said bolt clamping the movable top in any desired position of adjustment.
